Control boxes
For remote pumping applications, all four model submersible
pumps will require a control box (Figure 7).
For each model submersible pump there is an associated
control box. Reference Table 4 for the desired control box
and applicable heater. The heater size is determined by
the the full load amps the pump will draw.
These water-resistant control boxes provide electronic
overload protection a watertight enclosure and glands to
prevent water from leaking into the box, and a float switch
interface.
Each control box will require the use of
two SW-1WOPA
float switches, no plug, bare wires for direct connection to
the control box. Reference Figure 20 and Figure 21 for a
schematic reprensentation of each control box.
